14.13 Touch Screen Pressure
The Horner XL series OCS controllers have a resistive touch screen that allows mechanically detecting
touch events. The resistive touch screen works by measuring the resistance between two layers of
conductive film.
The following are required for this feature:
Minimum Firmware Version: 15.xx or later
Minimum OS Version: 2.6.35.49
Minimum Cscape Version: 9.80 SP1

Touch Screen Pressure
NOTE
: Touch creates contact between resistive circuit layers, closing a switch.
With a unique change to the touch monitoring firmware user can measure the pressure being exerted
on the touch screen. This feature has been added in some Horner XL series controllers. This allows the
OCS programmer to be notified of the touch pressure and it can configure the pressure required to
accept a touch event.
